After the 30-day trial
If you have not entered your billing information and you do not explicitly cancel, your account will expire. However, if you've already entered your billing information, you should cancel to ensure that you're not charged at the end of your trial.
The first time that you sign in to the Admin console after your subscription has expired, you'll be prompted to either renew now or confirm your cancellation. If you don't renew or cancel, user access may be suspended.
If you would like to delete your account, please review this article on deleting Google Apps.
